We conducted a large-scale experiment in Singapore and China to study whether the propensity for selfishness (alpha) and the tradeoff between efficiency and equality (rho) are the mediators from gender to subjects' behaviors in social games. We measure these two motives by using five distributing decisions in A-M Dictator Games and the results show that gender is a key determinant of these two motives and females are more fairness-oriented and selfish, less efficiency-oriented than males. We further provide evidence that these two motives significantly drive subjects' behaviors in various social games. Besides this indirect channel, gender also has a direct effect on subjects' behavior in various social games. Our findings provide deeper understandings of the motives of subjects' behaviors and gender differences in social games.
